I need to find and replace an element in an array. Is there any single php function for this?

I don't know of any simple function for finding and replacing in arrays, but you could always do something like:
$key = array_search($oldValue, $myArray);
if ($key) $myArray[$key] = $newValue;

You can simply use array_splice.
See example
$input = array("red", "green", "blue", "yellow");
array_splice($input, -2, 1, array("orange", "maroon"));
// $input is now array("red", "green", "orange", "maroon","yellow")

Your solution does not solve the problem of finding the element to be replaced.
Try This:
<?php
$myArray = array("John","William","Henry","Tom","Peter");
$newArray = array_splice($myArray, 2, 1, "Susan");
foreach($myArray as $key => $value) {
echo "$key - $value <br />";
}
?>
